Study and Discussion on Standard of Selenium-rich Soil in Gansu Province
-
Abstract
The establishment of local standard of selenium-rich soil is of significance to the development of selenium-rich industry.This paper analyzes the present situation of the establishment in the northwestern provinces. 304 samples of soil and wheat seed collected from Gansu province were studied by means of the lower limit and Se linear models of seed and soil, deducing 0.28×10-6 as the lower limit standard for selenium-rich soil.The study Lays a foundation for the establishment of the local standard and the scientific utilization of the selenium-rich soil in Gansu province.-
